HUMIDIFIER.

Specification of Letters Patent. Patented J an. 27, 1920.

AppIcation filed May 31, 1919. Serial No. 300,898.

To a-ZZ inkom t may concern:

Be it known that I, HARRY MIFFLETON ,Boemia a citizen of the United States, re-

siding at Petersburg, in the county of Dinwiddie and State of Virginia, have invented certain new and useful'Iinprovements in Humidifiers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in humidiers, and especially that class of humidiers intended to moisten fthe air in showcases or other inclosed receptacles where goods are stored that itis desirable to keep moist.

My invention is especially intended for use in connection with showcases or packing chests, or the like, intended to contain cigars or other forms of manufactured tobacco.

According to my invention I provide a flat pad in the general form of a lily leaf with a stem adapted to project down into a sol bottle, jar, or other vessel containing liquid. The lpad is made of porous material, and preferably comprises a central cloth core, with layers of blotting paper attached on either side thereof so as to form an evaporating surface for the liquid which is drawn up by capillary attraction from the bottle through the stem of the pad, and is evaporated in the air at the broadened portion of the pad which protrudes from the neck of the bottle or other receptacle in which the stem ofthe pad is immersed.

My invention will be more fully understood after reference to the accompanying drawings, in which like parts are indicated by similar reference symbols throughout the several views, and in which Figure 1 is a side elevation of the jar containing three of the pads which tovether resemble the form of a water-lily; anc

Fig. 2 is a plan view of one of thepads in the flattened or knock-down shape, parts being broken away to show the construction.

Referring to the drawings, each padcomprises a core A of one or more layers of flexible textile fabric. This fabric is preferably absorbent cotton, rendered such by suitable treatment. This absorbent core is reinfo; ced and stiffened by suitable flexible metal strip or strips B, so that the pad may be bent to any desired angle and remain so bent. This flexible core may be made of one or more thicknesses, as desired. y

Exterior to this core on each face and inclosing same and the metal strip or strips I secureva sheet of porous material C, such as blotting paper, which absorbs the moisture from the fabric and the moisture is evaporated by the flow of air past these moistened surfaces. This air becomes cooled, and also'more or less saturated with aqueous vapor, and thus air currents are created which will cause the moisture to be distributed throughout the inclosed receptacle in which the humidifier is placed.

I preferably secure the blotting paper layers exterior to the fabric layer, and the metal strip or strips by sewing, but the same may be riveted or secured in any other In order to facilitate the absorption, the absorbent fabric A preferably projects down from the lower end of the stem, as shown at a., One or more, or any desired number, of these pads may be placed in the receptacle` but for ordinary showcases'three will suffice, and these when placed in a jar or bottle and bent over the top of the neck of the jar or bottle will present the appearance ot' a water-lily.

In order to produce an artistic effect, the pads may be made of green, blue, red, or mottled, or of other color or colors.

The pads may be made flat or supcrposed one from another for convenience in shipment. and when put in the jar or bottle for use they may be bent over to any desired tilt, but the pad should preferably not be bent below the horizontal position, for otherwise they would cause a siphoning effect. Moreover, it is preferable to have the pads at an acute angle with the vertical to prevent the accumulation of dust on the same which will impair its eficiency as a humidifier.

Vhile I have shown the pads as substantially spoon-shaped in pla-n, they may be made of other forms if desired, and I do not mean to limit the invention to any particular form, nor do I mean to limit the invention to any particular porous fabric, or to Athe blotting paper sheath, since any suitable porous material may be substituted either for the fabric core or for the, blotting paper sheath.

Having thus described my invention what Iclaim and desire to secure by Letters Pat- 5 ent of the United States is l. A pad for use in humidiers'havng a head providing an enlarged evaporating surface, and a comparatively narrow stem, and comprising layers of exible absorbent 10 material, with a ieXible metal inlay between said layers reinforcing same, substantially as described.

2. A pad for use in humidiers having a head providing an enlarged evaporating lsurface, and a comparatively narrow stem, and

comprising a layer of absorbent textile fabric, and a flexible metal reinforce for same, substantially as described. l
